METALLIC CEILING.

SPECIFICATION forming part of Letters Patent No. 443,323, dated December 23, 1890. 7 Application filed March 4,1890. Serial N0. 342,562. (No model.)

T0 at whom it may concern.-

Be it known that 1, WILLIAM R. KINNEAR, a citizen of the United States, and a resident of Columbus, in the county of Franklin and State of Ohio, have invented new and useful Improvements in Metallic Ceilings; and I do hereby declare the following to be a full,

clear, and exact description of the same, ref-.

erence being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.

This invention relates to improvements in metallic ceilings; and it consists in the novel construction and arrangement of the parts hereinafter set forth and described.

In the drawings, Figure 1 is a plan view of one form of my improved ceiling. Fig. 2 is a plan view of a modified form of the same. Fig. 3 is an enlarged detail View in plan of a junction of the stiles of the form shown at Fig. 1. Fig. 4 is an enlarged detail View in plan of a junction of the stiles of the form Fig. 5 is a crosssection on the line 00 a: through the rail in Fig. 1. Fig, 6 is a cross-section on the line y 3 through the rail in Fig. 2. Fig. 7 is a detail view in section, showing one margin of a panel provided with a sealing strip. Fig. 8 is a detail View in section of a stile of the ceiling, showing an interposed sealing-strip.

The panels and moldings used in this ceiling are formed in the same manner as described in Letters Patent No. 388,285, granted to me the 21st day of August, 1888, to which attention is called for this part of the construction.

The improvement here described relates solely to the stiles or that portion extending between the moldings of the adjoining panels.

The stiles are formed by the margins A and The margins A are flat members adapted to extend partly over the furring-strips C for the purpose of receiving the fastenings for securing the panel. At either end of the margins A are formed the projections A, which form guides for the adjustment of the succeeding panels. The margins 13 are adapted to overlap the margins A, and are provided with the ribs B and B in the one form shown in the drawings and with the rib B only in the other form. In the first of these forms the rib B is formed merely to balance in the design the rib B and serves that purpose only. The rib B serves the purpose of forming a close joint between adjoining panels and also as a- 'which when the ceiling is painted becomes entirely concealed. Further, the purpose served by this rib is to form a channel for the reception of any sealing-material strips D, as shown at Figs. 7 and 8 of drawings, to form a completely air-tight joint for the purpose of preventing the admission of air to the space between the ceiling and the joists and flooring above it, and thus retard combustion. These strips. D are formed in short lengths and are constructed of some non-combustible material of such thickness as to be squeezed when the two margins are forced together.

The fastening devices most generally used by me are round-headed nails provided with ornamental washers E, as shown in Fig. 1 of drawings. These I place at regular intervals between the ribs 13 and I3 in such manner as to produce a design on the stile in harmony with the design of the ceiling. Another form of fastening device used by me is a small staple, as shown at Fig. 2 of drawings, as most desirable in that form of ceiling. By the use of this latter fastening I produce an effect that causes the ribs to resemble small bamboo rods.

For the purpose of stiffening the stile when the lighter construction shown at Fig. 1 is used I proxide the crossu'ibbing 13 between the ribs 13 and B at intervals, as desired. This cross-ribbing enters into and forms a great variety in the designs of the stiles. At the ends of the stiles they present a small depressed square when thepanels are combined. When it is desirable to provide a rosette or raised member at the junction of the stile in this construction, it is accomplished by stamping the material of this square up to form the same, or that most generally used by me of providing an ornamental washer or drop, through which the fastening for the corner is driven, drawing the washer down into the square. This latter method I prefer, as it allows for a greater variety of design in the corner-drops, which need not be constructed of the same material, but are usually made of a very soft and pliable metal.

To apply a ceiling thus constructed, the structure is first provided with the strips G, which block the work out and form receptacles for the panels to set in. The first panels are then putin place with the flat margins A toward the succeeding panels. The following panels are adjusted by placing the ribbed margins B over the Hat margins of the two adjoining preceding panels. Care should be taken in this part of the operation to adjust the rib 1-3 over the projections A on the margin A. In this position the fastenings, whether the round-headed nails or staples, are driven through the lapped margins.

\Vhen it is desired to produce a tire-proof or fire-retarding construction, the non-combustible strips 1) are used. To do this the strips are laid in the rib 13' before the panel is put in place. \V hen now the fastenings are driven, the strip is squeezed tightly and forms a close joint between the margins, and one which will not melt by heat nor allow air to pass to the smoldering wood above the ceiling. An obviousmodification of this con struction would be to form fellow panels, the one provided with only the margins A and the others with the margins B, and placing the first series in position and then the second, the margins of the latter covering those of the former.

What I claim is- 1. In a metallic ceiling such as described, stiles for dividing the same into panels, consisting in the combination of the margins of adjoining panels, those of the one being provided with guiding projections A and those of the other provided with a turned edge adapted to rest over the said projections, sub stantially as described.

2. In a metallic ceiling such as described, stiles for dividing the same into panels, consisting in the combination of the margins of adjoining panels, those of the one being fiat and those of the other provided with a ribbed edge adapted to rest upon the said flat margin, and eross-ribs B near the corner to form an ornamental feature at the j unetion of the stiles.

In a metallic ceiling such as described,

stiles for dividing the same into panels, consisting in the combination, with the margins of adjoining panels, those of the one being flat at the point of juncture and those of the other provided with a ribbed edge adapted to rest upon the said flat margins, of a compressible filling inserted in the said ribbed edge to form an air-tight joint between the margins and fastenings f r securing the margins together, substantially as described.

a. In a metallic ceiling such as described, stiles for dividing the same into panels, consisting in the combinatiomwith the margins of adjoining panels, those of the one being flat at the point ofj nneture and those of theother provided with a ribbed edge adapted to rest upon the said flat margin, of a strip of eon'ipressible and noncombustible material inserted in the said ribbed edge to form an airtight and fireproof joint between the margins and fastenings for securing the margins together, substantially as described.

5. In a metallic ceiling such as described, stiles for dividing the same into panels, consisting in the combination ofthe fiat margin A of one panel and the margin 15 of an adjoining panel provided with the rib 13 and an interposed strip of compressible material I), inserted in the said rib B, substantially as described.
